So what were they supposed to do with the money? Stuff it in a mattress somewhere?
No. Keep it in a very carefully governed trust fund where the trustees, who would be at arms length from the government, are charged with ensuring the purpose and health of the trust is constantly maintained. That's not to say they couldn't decide to lend money to the government as long as they were sure they could recover it within a resonable period of time.
That's exactly what they do. It's invested in the only security that meets those criteria.
